Title: Gas-liquid contacting device
Inventor: KITAMURA ISAMU
IPC: B01D53/18
Filed: 1981-11-26
Abstract: PURPOSE:To improve the performance of gas-liquid contact and to economize the energy driving power by shearing the foam which is discharged from an air diffusing pipe and ascends in liqid by the rotation of a perforated rotary plate utilizing the falling energy of the treating liquid. CONSTITUTION:When liquid to be treated is continuously charged into a vessel 1 further from the state in which the level of the liquid discharged through an introducing pipe 4 in the vessel is maintained constant by the rising height of a discharging pipe 6a communicating with the vessel, the liquid flows down through the pipe 6 into a pipe 6b by as much as the liquid charged into the vessel. The down flowing liquid gathers in a water collecting funnel 7 from which the liquid ejects through a water releasing port 8 and collides against water wheel vanes 10, thus rotating the revolving shaft 9 thereof. As a result, a perforated rotary plate 12 fixed to the shaft 9 rotates. The foam produced from an air diffusing pipe 3 ascends in the liquid and is agitated by the rotation of said plate 12. Then foam is made into small piece of the foam by the many projections and small holes 13 of the rotary plate, and is thereby diffused.

Title: Manufacture of semiconductor device
Inventor: HINO TERUSHIGE
IPC: C30B25/06
Filed: 1991-07-29
Abstract: PURPOSE:To form a stable metal film from a first wafer, by a method wherein, before the first wafer is treated, a target surface is sufficiently nitrified by making nitrogen gas flow. CONSTITUTION:A nitride layer is previously formed on a titanium target in a sputter chamber, before a wafer is treated. When Ar gas in the sputter chamber begins to flow at a treatment starting point A, an idling state simultaneously starts. In the idling state from A to A', the nitride layer on the titanium target surface is decreased. Before a first wafer is treated, nitrogen gas is made to flow in the idling state from A' to B, and mixed with the Ar gas. The idling state is changed to a deposit state at a first wafer treatment starting point B. After the titanium target surface is sufficiently nitrified in the mixed gas atmosphere, treatment of the first wafer is performed. Hence a stable titanium nitride film is formed from the first wafer.

Title: Resin coated silica particulate
Inventor: SAKAI KAZUHIKO
IPC: G02F1/1339
Filed: 1993-07-29
Abstract: PURPOSE:To prevent the generation of the damage and unequal orientation of oriented films by movement of spacers and the low-temp. foaming of a liquid crystal display device by coating the spacers with a fluororesin having a m. p. of a specific temp. or above at a thickness at which the ratio of the film thickness of the fluororesin layer/the grain size of silica particulates attains a specific range. CONSTITUTION:The silica particulates are coated with the fluororesin of >=200 deg.C m.p. at such a thickness that the ratio of the film thickness of the fluororesin layer/the grain size of silica particulates attains 1/100 to 1/3. An epoxy resin is usually cured at 160 to 200 deg.C and, therefore, the resin layer between the spacers and substrates flows out and the effect of preventing low-temp. foaming is lost when the epoxy resin melts in this temp. range. The fluororesin layer is compressed and deformed and the area of the contact parts of the silica particulates and the glass substrates widened, by which the movement of the spacers by vibration of ultrasonic waves used at the time of injecting liquid crystals or in a washing stage is prevented in a stage for controlling the gap of the liquid crystal panel in the range where the coating thickness of the fluororesin coating layer is 1/100 to 1/3 the grain size of the silica particulates.

Title: External mirror type gas laser tube
Inventor: NAKAMURA SHIGERU
IPC: H01S3/083
Filed: 1983-10-07
Abstract: PURPOSE:To obtain the titled laser suitable for ring laser gyroscope by a method wherein a discharge outlet is provided in the neighborhood of the center of a laser fine tube, and anodes in the neighborhood of Brewster windows at both ends, respectively; then the discharge outlet is arranged at the center of the cylindrical cathode in a vacuum casing. CONSTITUTION:The anode 5' is buried also in the neighborhood of the Brewster window 3' of the laser fine tube 1, anodes thus being provided in a total of two, and the discharge outlet 2'' is arranged at the center of the anode 6, i.e., nearly at the center of the fine tube. The construction of other parts is almost the same as that of the conventional laser tube. This construction brings gas flows 12 and 12' due to DC discharge which direct to the cathode from the anodes 5 and 5' in symmetry, and therefore the variation in the frequency of a laser beam passing through the laser fine tube is cancelled. Accordingly, in the case of constructing the external mirror type ring laser gyro, a piece of laser tube is sufficient, and the structure and the adjustment of the device are simplified.

Title: Column data selecting processing circuit
Inventor: SHIMOI HIROYUKI
IPC: G06F7/02
Filed: 1990-07-16
Abstract: PURPOSE:To attain the comparison between the column data and the target data including a special symbol added with a control symbol through hardware by deleting the control signal out of the special symbol included in the target data. CONSTITUTION:The record including a column needed for a host device, a special symbol showing the unconditional coincidence for selection of the column, and the target data needed for invalidation of the special symbol are inputted to the comparators 75-77 respectively. A detection means 87 performs the comparison of the special symbols including the control symbols if detected and transmits unconditionally a coincidence signal if the special symbol including no control symbol is detected. An abbreviation means 86 abbreviates the control symbol after deleting it out of the target data. A flag holding means 82 holds a flag when the coincidence is secured between the abbreviated target data and the column data and then erases the flag if no coincidence is secured. A control means 85 decides the discordance between the column data and the target data to set a flag to the means 82 then compares both data with each other. When the flag of the means 82 is erased, the means 85 repeats the comparison of data thereafter and decides the coincidence between both data if the means 82 displays a flag when the data are not available any more. Thus the comparison is attained between the column data and target data including a special symbol.

Title: Single side band transmitter which has compensated filter characteristic
Inventor: OGAWA NOBUO
IPC: H04B1/04
Filed: 1980-12-26
Abstract: PURPOSE:To obtain a flat frequency characteristic as a whole, by compensating a drop of a shoulder characteristic of an intermediate frequency filter of a receiver, by a peak of a pass band end of an unnecessary side band rejecting  filter of a transmitter. CONSTITUTION:In an SSB transmitter, a peak of at least 3dB or more is set to a pass band end of a filter in order to reject an unnecessary side band. It is disadvantageous from the viewpoint of the adjacent selectivity to widen the band width of the filter of a receiver althrough it is same as for its overall characteristic, therefore it is more effective that this correction is executed by the side of a transmitter. In this regard, as for a ripple in the pass band of a filter, + or -2dB is allowed in general, therefore, it is desirable to set a peak of at least 3dB to the pass band end.

IPC: G11B7/00
Filed: 1993-07-01
Abstract: PURPOSE:To detect the deviation of position of recording data by counting the number of clocks generated by a PLL between the respective signals of ATIP-Sync successively detected during the write operation of data to a disk. CONSTITUTION:When the detection of PLL slip is desired to start and the command is given from a microcomputer, a lock-in detection circuit 12 confirms that the PLL is in a lock state and issues a reset instruction for a synchronization reset circuit 13. When it is received, the synchronization reset circuit 13 resets a counter 11 for slip detection only once based on input data from a Sync synchronization counter (a). When the PLL of a clock generation circuit 8 generates the slip of one clock for instance, the Sync synchronization counter (a) is reset at 82 counts while it is to be reset at 83 counts. The difference of the output values is calculated by a subtractor 14, sent to the microcomputer as a slip amount and detected.

Title: Antenna
Inventor: TSURUMARU SHINOBU
IPC: A47B88/493
Filed: 1982-10-28
Abstract: PURPOSE:To change tuning frequency by forming an antenna element like a loop, supporting a part of the antenna element so as to change its angle to the plane of polarization and changing the angle. CONSTITUTION:An element 30 is electrically connected to elements 10, 20 through springs 41, 42 to form an antenna loop. The whole peripheral length of the loop is a little over 1m which is the loop length of 0.3-0.35 wavelength at the low band of a VHF band, and the antenna loop starts parallel resonance at about 150MHz. Matching by a matching circuit 50 allows the antenna to turn to a band tuning type and cover the whole areas. Since the angle theta of the element 30 to the elements 10, 20 can be changed, the coupling capacity is changed when supposing that the loop is a distribution constant line. Thus, the change of the angle theta can alter the tuning frequency at the low band and cover the whole areas. Thus, an antenna with superior characteristics can be obtained in spite of the small-sized one.
